前言

在做视频站,往往不想让用户看到视频真实地址,于是就有了这个代码

代码示例

html 代码

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>videojs</title>
</head>
<body>
<video class="video-js vjs-big-play-centered"   controls data-setup="{}" width="960" height="400" preload="auto"  >
    <source src="https://richerdyoung.com/test.php"  type="video/mp4"></source>
</video>
<link href="//cdn.bootcss.com/video.js/7.0.0-alpha.1/alt/video-js-cdn.css" rel="stylesheet">
<script src="//cdn.bootcss.com/video.js/7.0.0-alpha.1/video.min.js"></script>
</body>
</html>

test.php

<?php

ini_set('memory_limit', '1024M'); //修改脚本的最大运行内存
set_time_limit(600); //设置超时限制为 10分钟

//视频地址可以换成你的来测试
$play_url = 'https://richerdyoung.com/test.mp4';
//输出视频流 
outPutStream($real_paly_url);die();

//输出视频流
function outPutStream($videoUrl) {
    if(!$videoUrl){
